The unit used for measuring electrical current is called a(an):

Electrode
Volt
Discharge
Ampere

Correct Answer

A. Ampere

Explanation

The unit used for measuring electrical current is called ampere. Ampere is the SI unit of electric current, symbolized as A. It is named after the French physicist André-Marie Ampère. The ampere is defined as one coulomb of charge passing through a point in a circuit per second. It is commonly used to quantify the flow of electric charge in electrical circuits.

This is the unit of measurement for measuring electrical pressure or EMF?

Switch
Volt
Ampere
Electrode

Correct Answer

A. Volt

Explanation

The volt is the unit of measurement for electrical pressure or electromotive force (EMF). It represents the amount of potential energy per unit charge that is available in an electrical circuit. The volt is used to measure the force or intensity of an electric field, and it is commonly used in various applications such as electronics, power systems, and telecommunications.

Material that electricity can travel through easily is called a

Conductor
Insulator
Relay
Resistor

Correct Answer

A. Conductor

Explanation

A conductor is a material that allows electricity to flow through it easily. It has free electrons that can move freely within the material when a voltage is applied. This movement of electrons creates an electric current. Examples of conductors include metals like copper and aluminum. In contrast, insulators are materials that do not allow electricity to flow through them easily. They have tightly bound electrons that do not move easily. Relays and resistors are components used in electrical circuits but do not describe materials that electricity can travel through easily.

A circuit is a path taken by a current. A path with no breaks is called a

Closed-circuit
Capacitor
Circuit Breaker
Variable Resistor

Correct Answer

A. Closed-circuit

Explanation

A closed circuit is a path taken by a current where there are no breaks or interruptions. In a closed circuit, the current flows continuously from the power source through the circuit components and back to the source. This allows the electrical energy to be transferred and used effectively.

If there is a break in the path the current follows, the circuit is incomplete. A break in the path is called an

Open circuit
Parallel Circuit
Load Rejection
Electromotive Force

Correct Answer

A. Open circuit

Explanation

An open circuit refers to a situation where there is a break or interruption in the path that the electric current follows. In other words, the circuit is not complete, and the current cannot flow through it. This can happen due to a disconnected wire, a switch in the off position, or a faulty component. In an open circuit, the flow of electricity is halted, and no electrical energy can be transferred or used.

Materials that do not allow electrical charges to pass through them easily are called

Insulator
Conductor
Voltage
Waveform

Correct Answer

A. Insulator

Explanation

Insulators are materials that have high resistance to the flow of electrical charges. They do not allow electrical charges to pass through them easily, preventing the flow of electric current. This property makes insulators useful in applications where the goal is to prevent the loss of electrical energy or to protect against electric shocks. Some common examples of insulators include rubber, plastic, glass, and wood.

Lightning is caused by the build-up of electrical charges in a cloud, also known as static electricity.

True
False

Correct Answer

A. True

Explanation

Lightning is caused by the build-up of electrical charges in a cloud, also known as static electricity. This build-up occurs when there is a separation of positive and negative charges within the cloud. As the charges continue to accumulate, the electrical potential difference between the cloud and the ground increases. Eventually, this potential difference becomes so great that it overcomes the insulating properties of the air, resulting in a rapid discharge of electricity in the form of lightning. Therefore, the statement "Lightning is caused by the build-up of electrical charges in a cloud, also known as static electricity" is true.

9.

Parallel circuits have only one path.

True
False

Correct Answer

A. False

Explanation

Parallel circuits have multiple paths for the flow of electric current. In a parallel circuit, the components are connected in such a way that each component has its own separate path to the power source. This allows the current to divide and flow through each component independently. Therefore, the statement that parallel circuits have only one path is incorrect.

10.

The current always travels from the negative electrode to the positive electrode.

True
False

Correct Answer

A. True

Explanation

In an electrical circuit, current flows from the negative electrode (also known as the cathode) to the positive electrode (also known as the anode). This is because the electrons, which carry the current, are negatively charged and are attracted to the positively charged electrode. Therefore, the statement that the current always travels from the negative electrode to the positive electrode is true.
